Throwing Exception error

Im having problem within a method throwing an IndexOutofBoundsException. I tried a few different things but I still recieve this error:

SortedDoubleList.java:39: cannot find symbol

symbol : class IndexOutofBoundsException

location: class SortedDoubleList

else throw new IndexOutofBoundsException("Index not within parameters.");// it points to the Index in IndexOutOfBounds...

publicvoid ListInsert(int pos,int newItems)

throws IndexOutOfBoundsException, RuntimeException

{

if (numItems >=List_Size)

thrownew RuntimeException("List is full.");

if (pos >=1 && pos <= numItems)

{

for (int i=numItems; i >= pos; i--)

items[i]= items[i-1];

items[pos-1]=newItems;

numItems++;

}

elsethrownew IndexOutofBoundsException("Index not within parameters.");

}
